Abstract: The present disclosure provides a structured light projection optical system for obtaining 3D data of an object surface, which includes a structured light projection optical part configured to project a plurality of patterns onto an object or a screen, and an imaging optical part configured to obtain 3D data by photographing the patterns being projected from the structured light projection optical part, wherein the structured light projection optical part includes a plurality of light sources, and a plurality of pattern masks, wherein as the plurality of light sources are turned on and off, the pattern mask matches any one of the plurality of light sources illuminating a light, and the plurality of patterns are projected on the object or the screen by the pattern mask. Accordingly, various patterns can be effectively projected, real-time measurement can be easily performed through a quick pattern change, and the accurate 3D data can be obtained.
